The gasket kit contains 8 pieces of each material, sized for the EXT65 Keyboard. We recommend getting a kit if you have bought an EXT65 and you want to do a bit of testing and research, as we don't know when we will have another stock of these again.
Note: These may also be compatible with other boards, if placed properly and cut to size. The thickness is 1.5mm which gets compressed with pressure.
Please note that shipping is charged separately per vendor.
